Limit theorems for integer partitions and their generalisations

Ralaivaosaona, Dimbinaina 03 1900 (has links)
Thesis (PhD)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: Various properties of integer partitions are studied in this work, in particular the number of summands, the number of ascents and the multiplicities of parts. We work on random partitions, where all partitions from a certain family are equally likely, and determine moments and limiting distributions of the different parameters. The thesis focuses on three main problems: the first of these problems is concerned with the length of prime partitions (i.e., partitions whose parts are all prime numbers), in particular restricted partitions (i.e., partitions where all parts are distinct). We prove a central limit theorem for this parameter and obtain very precise asymptotic formulas for the mean and variance. The second main focus is on the distribution of the number of parts of a given multiplicity, where we obtain a very interesting phase transition from a Gaussian distribution to a Poisson distribution and further to a degenerate distribution, not only in the classical case, but in the more general context of ⋋-partitions: partitions where all the summands have to be elements of a given sequence ⋋ of integers. Finally, we look into another phase transition from restricted to unrestricted partitions (and from Gaussian to Gumbel-distribution) as we study the number of summands in partitions with bounded multiplicities. / AFRIKAANSE OPSOMMING: Verskillende eienskappe van heelgetal-partisies word in hierdie tesis bestudeer, in die besonder die aantal terme, die aantal stygings en die veelvoudighede van terme. Ons werk met stogastiese partisies, waar al die partisies in ’n sekere familie ewekansig is, en ons bepaal momente en limietverdelings van die verskillende parameters. Die teses fokusseer op drie hoofprobleme: die eerste van hierdie probleme gaan oor die lengte van priemgetal-partisies (d.w.s., partisies waar al die terme priemgetalle is), in die besonder beperkte partisies (d.w.s., partisies waar al die terme verskillend is). Ons bewys ’n sentrale limietstelling vir hierdie parameter en verkry baie presiese asimptotiese formules vir die gemiddelde en die variansie. Die tweede hooffokus is op die verdeling van die aantal terme van ’n gegewe veelvoudigheid, waar ons ’n baie interessante fase-oorgang van ’n normaalverdeling na ’n Poisson-verdeling en verder na ’n ontaarde verdeling verkry, nie net in die klassieke geval nie, maar ook in die meer algemene konteks van sogenaamde ⋋-partities: partisies waar al die terme elemente van ’n gegewe ry ⋋ van heelgetalle moet wees.

Criptografia RSA: da teoria à aplicação em sala de aula / RSA Cryptografy: from the theory to a classroom aplication

Silva, Evelyn Gomes da 26 April 2019 (has links)
Esta dissertação tem por objetivo apresentar a Criptografia RSA, que é o método de criptografia mais utilizado no mundo atualmente. Iniciamos a dissertação com um breve histórico sobre a criptografia e em seguida introduzimos a teoria matemática empregada no método pertencente a teoria dos números. Finalizamos a dissertação com a descrição de uma aplicação simples do método levado para uma sala de aula do ensino médio. Este texto pretende introduzir o tema de maneira simples e por esta razão, fazemos uso de muitos exemplos. Esperamos ainda que o leitor compreenda o que torna este método eficiente e seguro. / The main goal of this work is to introduce the RSA Criptography that is the most used method in Criptography nowadays. We begin the dissertation with a brief introduction about criptography and then we discuss concepts from number theory used in the method. Finally we present a description of a simple application of Criptography made in a High school classroom. This text intend to introduce the subject in a simple way for this reason we present several examples. We hope that the reader have the comprehension of the methods and of its security.

Criptografia RSA: a teoria dos nÃmeros posta em prÃtica / RSA encryption: number theory put into practice

Lana Priscila Souza 11 June 2015 (has links)
CoordenaÃÃo de AperfeÃoamento de Pessoal de NÃvel Superior / Desde o advento da escrita, o envio de mensagens secretas tem sido uma importante maneira de guardar sigilo de informaÃÃes confidenciais. A arte de elaborar mensagens a partir de cÃdigos secretos surge na figura da criptografia que, com o passar do tempo, estende os seus serviÃos Ãs transaÃÃes comerciais realizadas pela internet. O principal algoritmo utilizado pela internet recebe o nome de RSA. Assim, a criptografia RSA codifica nÃmeros de cartÃes de crÃditos, senhas de bancos, nÃmeros de contas e utiliza para isso elementos de uma importante Ãrea da MatemÃtica: a Teoria dos NÃmeros. / Since the advent of writing, sending secret messages has been an important way to maintain confidentiality of sensitive information. The art of crafting messages from secret codes appears in the figure of encryption that over time extends its services to commercial transactions over the Internet. The main algorithm used by the internet is called RSA. Thus, the RSA Encryption encodes credit card numbers, bank passwords, account numbers and uses for that elements of an important area of mathematics: number theory.

On a conjecture involving Fermat's Little Theorem

Clark, John 13 May 2008 (has links)
Using Fermat’s Little Theorem, it can be shown that Σmi=1 i m−1 ≡ −1 (mod m) if m is prime. It has been conjectured that the converse is true as well. Namely, that Σmi=1 i m−1 ≡ −1 (mod m) only if m is prime. We shall present some necessary and sufficient conditions for the conjecture to hold, and we will demonstrate that no counterexample exists for m ≤ 1012 .
